Organic/Metal-Organic Materials Chemistry

Our research focuses on the synthesis and characterization of photofunctional organic/metallo-organic materials for optical limiting and/or photodynamic therapy applications.

Optical limiting materials are nonlinear optical materials that can transmit most of the light at low intensities, but absorb, reflect, refract, or scatter light at high incident intensities for the protection of human eyes and optical sensors. Nonlinear absorption, particular reverse saturable absorption and two-photon absorption, has long been recognized as useful for optical limiting, however, it is not currently possible to a-prior design molecules that exhibit large nonlinear absorption. To remedy this deficiency, the relationship between nonlinear absorption and molecular structure must be explored. Organic/metallo-organic complexes are ideal candidates for this application because of their large, fast, and broadband optical nonlinearity. In addition, the chemical structures of these complexes can be easily modified. The complexes currently under study include nanoparticle-expanded metalloporphyrin composites, transition-metal terpyridyl acetylide complexes (Figure 1), polyads, and dendrimers, and stilbazolium derivatives. This project involves organic synthesis, spectroscopic studies (UV-Visible absorption, transient absorption, fluorescence and phosphorescence), and nonlinear optical characterization (using degenerate four wave mixing, Z-scan and nonlinear absorption techniques).

Photodynamic therapy (PDT) is an emerging cancer treatment method based on the interaction of light, a photosensitizer, and oxygen. It has specific selectivity comparing to other cancer treatment modalities. Unfortunately, limitations of current photosensitizers, such as toxicity, inability to treat deeply situated cancers, cutaneous photosensitivity, and water insolubility prevent the widespread use of PDT to date. In order to overcome these limitations, a series of water-soluble pentaazadentate porphyrin-like rare-earth complexes (Figure 2) and core-modified Texaphyrins that can absorb near-infrared light are being synthesized and investigated in my group. A variety of spectroscopic and structural methods including UV-VIS, IR, MS, NMR, X-ray crystallography, fluorescence and phosphorescence spectroscopy, transient absorption, and spin-trapping electron paramagnetic resonance (EPR) spectroscopy are being used to characterize the structures and to investigate the photophysics and photosensitization mechanisms of the complexes.
